Frugal Mesh // Work in Progress

Ok .. so quite some time back, I made an island in Vue5 Infinite. Here is the island imported into trueSpace 7.51. and as you can see, the mesh is very complex and poly-heavy. This makes a lot of sense for a program like Vue.. it's ready to have mountains or valleys at the touch of a button. And makes for some very nice renders... However, I'm hoping I'll be able to use trueSpace to modify my mesh in to an elegant sufficiency for realtime game rendering.
I'd grateful for any and all help comments and crits while I try to do this! :)

Here's what I've done so far.. I'm willing to back up if I'm going down the wrong track. But, I decided that for starters I'd like a simplification of just one part of the island - the plateau, which is relatively flat.
So, I decided to pretend to be Slartibartfast (but with out the fiords) :D
I moved over the model side, and tried to neatly cut the plateau off the top of the island. Uhm.. not as easy as I thought.. boolean subtract was 'reluctant'
However, I discovered Select Using Rectangle and Separate Selected Part of Object .. Rip!! wow - that worked! although.. hmm, a bit raggedy...
I decided to neaten up the edges with some point editing, although that means there is no way of reattaching it to the rest of the island... I'm willing to back up if that was a bad idea...

Now - where's the easy button when you want it? :D |

Couple of quick and dirty options for you: Boolean subtract a non-intersecting cube (ie a simple cube primitive that isn't touching anything else). Bam! any un-necessary edges (as tS sees it) are removed. Other option that springs to mind is, if you have the PolyTools suite of plugins, the Tesselate and Un-Tesselate plugins will do a great deal of what you want. |

Have you tried the normal map and simplify mesh tool? That's the first thing I'd try. :) |

Curiously, I searched for simplify mesh tool and "simplify mesh' even just "simplify" it came back with no results.. so I concluded that I must have hallucinated that there had been such a tool :D
I'll try again .. otherwise.. perhaps an image of the icon would help me find it?:rolleyes:
EDIT: Hmmm.. I found something called Polygon Reduction Tool ..... |

Hi Butterpaw,
There are two tools one in the model and one in the workspace view.
In the model view it is called polygon reduction tool and in the workspace view it is simplify mesh.
I hope uploading the attachements has worked ;) The pics should help finding them.
Regards

If you mean the images.. yes - and thanks.. had not spotted the tool in the workspace.. don't know why the icon finder wasn't helping except possibly because I didn't know the new name of the tool in model side
thanks! :)
(instead of my periodic chart of the elements... I think I'd like a tS chart of the icons on my wall :D ) |

Funny there is a chart included with 7.0, it had come with the manual. I wonder if Caligari can give us permission to post the chart here? That way new users can print it for their own use. |

BP there are some excellent tools on the Workspace for manipulating and editing a big heightfield - particularly the soft selection tool.
How big is your mesh? I've found that tS 7.5 happily deals with quite high resolution meshes - especially so on the workspace side. |

Thanks W!ZARD it's about 25,000 polys ... about a quarter of the size I started with in Vue, and I plan to reduce it a LOT more :p
I'll check out those tools ;) |

Well I have been going over this for a while and today seemed a lot better.. after some discussions about the game engine, it was decided that we'd probably do better with a 'static mesh' and could go ahead and put in the entire island.
I think the simplify mesh tool in workspace does the best job I've seen on this.. while vue does allow the degree of simplification to be chosen, and model side trueSpace appears to allow a simplification without choice of how much, Workspace in trueSpace gives a variable slider (similar to Vue) BUT with realtime view of the changes. This really helps in making a choice how far to take it.. and .. one can back up if it's too much.. as often as one likes before committing. :) Nice feature!
So here's the level I chose.. this is 2541 vertices.. not sure if it's possible to get a poly count.. I'm hoping with bump-mapping and good textures this can look fairly convincing.
Reactions? Suggestions? all welcome .. and thanks ^_^

Butter the so called simplification tool
in model side is not a tool its an illness !!!!:p
Never worked !
So all what comes out of workspace side that works
is a warm welcomed change !:D
Nevertheless I would use the simplifiaction in
Vue !
Just posted about the Vue Inf PLE version in the tree thread !
It does even save trees from the tree editor .... so it should
work for terrains too !

Thanks, yes it does (I have Vue 5 infinite) but when you get down the the number of verts I've reached with tS Workspace.. in Vue it sort of loses its identity.. the shape is not so good.. so.. comparing those two .. Workspace came out better, but of course there is newer Vue which might be much improved... ^_^ |

Not sure if this is useful but there is the Object Information in the Objects - Script objects library. With this object you can see the Vertice and Face count of selected object. |

Butter !
Its not a question of Vue 5 or 6 inf !
They are both working well !
The meshes you get when you save out with reduced polys is alot better
from vue then with what you get from workspace.
If you want to know what poly count that realy is
import it into Vue and doubleclic it for the save option and
there it tells you!
This whole mountain is arond 5000 polys and pretty low texture size
As you can see the polymesh is much better in this workspace view !
This is a Vray render from truespace.
(material 800x800 for the whole mountain) |

trueBlue - thanks for that information .. I 'll go look ^_^
Rayman - ok.. I'm going to experiment some more with Vue as well ^_^ |
